Was in the garage for the whole afternoon working out the problem with a 250 Honda Rebel. It was a hard start when cold from the time the lady bought it. If she pumped the throttle several times, the accelerator pump would richen it up enough to start but it required several restarts before she could keep it going. After it was warmed up, all was well.
If she used the choke, the engine would not start when cold, even after it had been running for a time. Using the choke when warmed up it would sometimes start.
After a lot of cleaning passages and inserting wires and carb. cleaner in order to identify passages, it seemed obvious that the 1/8" hole into the side of the enrichener jet passage was the problem. That hole was large enough that I could not see how there would be sufficient low pressure created above that point to lift fuel, emulsify and deliver out the enrichener discharge port.
I made a screw to fit the hole, inserted, reinstalled the carb. (
), miserable job, and it starts on a touch of the button.
They ordered an aftermarket H4 headlight assembly with bucket to replace the original unit having a 35 Watt Stanley bulb inside a "sealed beam". The light was poorer than my AA battery LED pocket flashlight but with a 35 Watt (60 Watt H4 QI bulb equivalent) HID the light is fantastic. She may not like it though as it lacks that orange, sitting by 13th Century monk's candle charm.
The bike will now start when cold, lights up the road, so now to add some additional LED lights to improve visibility and she can take it home. As long as it doesn't snow as it has been threatening to do again.
The main reason for the HID is power consumption as the HID uses 35 Watts as did the original headlight. I didn't want to push the little charging system enough to try to run a 55/60 Watt H4 bulb as was hoping to have enough capacity left to run some additional LED lights so the bike can be seen at night.
Also made an addional breather for the MG's rocker cover as they suffer from having only a 3/8" breather hose.
Next resealing the MG's differential carrier and then making up a suction pump to connect to the crankcase of my ST1100. I'm interested in trying low crankcase pressure to see if it has a noticeable benefit. This is common practice on race cars and old English twins so being retired.....
